Abstract
Laboratory tests in thermo-hydraulic cells that simulate the conditions of the sealing material in a radioactive waste repository are very useful to identify and quantify processes taking place in the engineered barrier. This kind of tests have gone on at CIEMAT for the last 20 years, evolving from simple designs in which just temperatures inside the material were measured, to the current designs that involve the measurement of temperature and relative humidity, total pressure and water intake. Tests kept running for different periods of time (up to several years) and the analysis of the material upon dismantling included mineralogical, geochemical, microstructural, hydro-mechanical and chemical studies, what allowed gaining insight into the time evolution of the properties of the barrier.
